I miss the simplicity of everything back in the 90's. The market wasn't flooded with a crazy amount of supplements and whatnot. People dose this & that and end up killing things because they think they're supposed to add everything. I had a simple wet dry that I never had to mess with, no skimmer (they were air stones then), never used RODI water (just stress coat), and I had a mix of play sand and crushed coral. I neglected the heck out of that tank and yet when I tested the water once every few months, it was good.. I think with sooo many things on the market now, it confuses people and they tend to skip the basics and go right to advanced, with undesirable outcomes.
